Mathematics 4th ESO
Our School Project
GEP (GEneració Plurilingüe) - First Year
1. Contest of measures
Working in groups of 4 or 5
Using the measuring instruments (tape measure, containers, weighing scales, chronometer and protractor), the students have to get familiar with the basic measures.
The students have to:
-Cut a string of length 1 m.
-Fill a container with a litre of water.
-Fill a bag with 1kg of sand.
-Calculate 1 minute.
-Draw an angle of 30º.
Working in the playground, the students have to estimate the following lengths without the measuring instruments.
-The length, width and area of the ping-pong table.
-The volume of a glass.
-The weight of a dictionary.
-The time that a student takes while walking from one bench to the other.
-The angle formed by the branches of the olive tree.
After their estimations they have to compare their results with the real ones and comment them with their classmates.
*They can not use any of the measuring instruments.
2. Classifying equations depending of the number of solutions
Review how to solve a linear and a second degree equations and classifying equations depending on the number of solutions.
The students will complete the undertanding on basic equations.
They will be able to analyze equations.
- Matching conditions to write sentences to predict the number of solutions of equations.
-Writing conclusions and expressing conditions.
- Organizing flashcards they will have a mindmap of how to solve second degree equations and then they will write the final production: an instructive text explaining how to solve a second degree equation and the number of solutions it will have.
3. Solving equations and polynomial long division
Students divided in groups of four, have to make a presentation to their classmates about solving equations. Each group have to prepare a lesson about a different kind of equation.
They have to distribute the different roles: Maths expert, secretary, public relations and ITC expert.
They will be teachers for one day!
A day at class!
